IMPROVEMENT IN NURSING-BOTTLES.

Specification forming part of Letters Patent No. 166,747, dated August17, 1875; application filed June 14, 1875.

To all whom it may concern:

Be it known that I, JAMns J. CHRISTIE, of the city and county of Camden,and State of New Jersey, have invented a new and useful Improvement inNursing-Bottles; and I do hereby declare the following to be a clear andexact description of the nature thereof, sufficient to enable othersskilled in the art to which my invention appertains to fully understand,make, and use the same, reference being had to the accompanying drawingsmaking part of this specification, in which- Figure 1 is a side view ofthe device embodying my invention. Fig. 2 is a top or plan view thereof.Fig. 3 is a longitudinal section thereof in line a: a, Fig. 2. Figs.4and 5 are face and side views of a valve employed in the invention.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists in a nurse-bottle, which is constructed of a body,having at one end a neck for attachment of the nursing-nipple, orstopper carrying the same, and a nipple integral with the body, upon thesurface of the body proper of the bottle, for securing a vent-cap, thelatter permitting the entrance of air, and thereby causing easy suctionto the child, and ready flow ofthe liquid food, the location of the ventbeing such that the ordinary nipple, perforated stopper, or cap may beapplied to the mouth of the bottle, and the cap may be readily attachedto the bottle, and possess a convenient and tight joint.

Referring to the drawings, A represents a nurslng-bottle, consisting ofthe glass body A and neck B. One side 0 of the body is flat, andconstitutes what may be termed the bottom of the bottle, and on whichthe bottle stands or is rested. The neck B extends upwardly or at anangle to the body A, and the end thereof may have fitted directly to ita nipple, or it may receive a stopper for attachment of a nippleattached to a long flexible tube, and also the conveying-tube whichprojects into the bottle.

It will be seen that when the bottle stands on its side 0, it occupies ahorizontal position, in contradistinction to the vertical positionheretofore assumed by a bottle of the same class, and thus it isconvenient for filling, and is not liable to overturn. Furthermore, thebottle is always in position to be presented to the child, and does notrequire, therefore, to be turned sidewise. Moreover, if the child isleft to itself, the bottle may be placed on a table or chair, and bymeans of the flexible tube the child can feed itself without danger ofoverturning the bottle.

On the upper side of the body A, or side opposite to the bottom 0, thereis formed a nipple, D, which is integral with the body, and projectstherefrom, and the surface thereof is threaded for the attachment of ascrewcap, E, in which is avent or opening, a, which cap may be fitteddirectly on the nipple D, or on a supplemental cap or collar, b, screwed011 the nipple. The vent may, however, consist of notches orperforations formed in the cap and collar 1), which will be uncoveredand opened by unscrewing the cap. Within the cap there may be fitted avalve, F, which opens inwardly, in order to form a communication betweenthe atmosphere and body A through the vent a, and closes against thevent in order to close said communication.

It will be seen that when the child draws on the mouth-piece or nipple,the air enters the bottle through the vent a, whereby suction is easilyperformed by the cllild, and the muscles of the face are greatlyrelieved, and the liquid food flows freely. When the bottle is turnedsidewise, the contents thereof cannot escape through the vent-opening,owin g to the diminutive size thereof; but if there is any liability ofthe escape of the contents through said opening, the valve within thecap will prevent the same; or, if there are openings or notches in thecap and collar or nipple, .the proper rotation of the cap will closesaid openings or notches.

Since the nipple projects from the body, and the cap is screwed oversaid nipple, the joint between the parts is rendered tight and reliable,and leakage thereat is prevented.

I am aware that the stoppers or caps of the body, upon the surface ofthe body. proper nursing-bottles have been provided with vents of thebottle, for securing a vent-cap. substanand valves; therefore,1disclai1nsuch features. tially as and for the purpose set forth.

Having thus described my invention, what I JAMES J CHRISTIE claim asnew, and desire to secure by Letters Patent, is Witnesses:

The nurse-bottle constructed of a body with JOHN A. WIEDERSHEIM, a neckat one end, and a nipple integral with A. 1?. GRANT.
